Free QR Code Generator

Yes. It is completely free, there is no sign-up, and there is no watermark on your code. You can make and download as many QR codes as you like, and use them for personal or commercial work.

No. These are static QR codes, so the data is baked into the image itself. They never expire and there is no cap on how many times they can be scanned. The one trade-off is that you cannot change where a static code points after you print it. If the destination changes, you generate a fresh code.

Yes. Upload a logo and it sits in the centre of the code with a clean backing so it stays readable. When you add a logo, bump the error correction up to High so the code still scans with part of the middle covered. Keep the logo to roughly a quarter of the width and test-scan before you print.

A lot. This tool builds codes for a website link, plain text, a Wi-Fi network, a contact card (vCard), a UPI payment, an email, a phone number, a WhatsApp chat and a map location. Each option formats the data the right way so phones recognise it and offer the correct action.

It can, as long as there is strong contrast between the code and its background. Keep the pattern dark on a light background, not the other way around, and avoid pale colours. If the contrast is low, or you invert it, many cameras will struggle. When in doubt, test with a couple of phones before printing.

As a rule of thumb, keep it at least 2 by 2 cm (about 0.8 inch) for something scanned up close, and larger for posters read from a distance. A common guide is a width of about one-tenth of the scanning distance. Always leave the clear quiet margin around it and do not stretch it out of square.

Error correction lets a code still read when part of it is dirty, damaged or covered. There are four levels: Low, Medium, Quartile and High, recovering roughly 7, 15, 25 and 30 percent of the code. Higher levels are more robust but pack the pattern more densely. Use Medium for clean screens and print, and High whenever you add a logo.

Use PNG for quick use on screens, in documents and in most designs. Use SVG for print and large formats, because it is a vector that stays razor sharp at any size, which matters when a code has to scan cleanly on a banner or a package.

Nothing you type is stored or sent to a server. The QR code is drawn entirely in your browser using client-side code, so your links, passwords and contact details never leave your device. That makes it safe for Wi-Fi logins and other sensitive details.

Choose the Wi-Fi option, enter your network name, pick the security type (usually WPA), and type the password. The tool formats it so that scanning the code offers to join the network, with no need to read out or type the password. It is handy for cafes, offices and guest networks.

Not with a static code like the ones here, because the data lives in the image and there is nothing pointing back to a server to count. Scan tracking, editable destinations and campaign analytics need dynamic QR codes served through a system. That is the kind of software we build at Techliphant if you need it at scale.
